Enables mercury ion binding activity and protease binding activity. Involved in several processes, including cellular response to growth factor stimulus; cellular response to mercury ion; and cellular response to peptide. Located in basement membrane and extracellular space. Used to study diabetic angiopathy; hypertension; and renovascular hypertension. Biomarker of several diseases, including artery disease (multiple); calcium oxalate nephrolithiasis; iron deficiency anemia; membranoproliferative glomerulonephritis; and ureteral obstruction. Human ortholog(s) of this gene implicated in calcium oxalate nephrolithiasis; membranoproliferative glomerulonephritis; and spondylometaphyseal dysplasia corner fracture type. Orthologous to human FN1 (fibronectin 1). [provided by Alliance of Genome Resources, Apr 2022]
